# REST API

### Requirements <a href="#requirements" id="requirements"></a>

To use the latest version of the REST API you must be using:

* WooCommerce 3.5+.
* WordPress 4.4+.
* Pretty permalinks in `Settings > Permalinks` so that the custom endpoints are supported. **Default permalinks will not work.**
* You may access the API over either HTTP or HTTPS, but *HTTPS is recommended where possible*.

If you use ModSecurity and see `501 Method Not Implemented` errors, see [this issue](https://github.com/woocommerce/woocommerce/issues/9838) for details.

### Authentication

This API follows WC Authentication. See WC doc on how to set-up consumer key/secret:

{% embed url="<https://woocommerce.github.io/woocommerce-rest-api-docs/#authentication>" %}

### Permission:

If your only using the api to view data, just set the user permission to `read`.

If your only using it for manipulating data then use `write`.

If you want both then set permission to `read/write`.
